PT Pertamina Hulu Rokan (PHR) has lost an estimated 2 million barrels of oil production following a gas supply disruption caused by a leak on the Grissik–Duri pipeline, with authorities expecting gas flows to return to normal and oil output to recover within days.
The Ministry of Energy and Mineral Resources said the Grissik–Duri gas pipeline, operated by PT Transportasi Gas Indonesia, had reached maximum operating capacity and would resume normal operations by Thursday.
“Last night at midnight, the gas flow was fully opened and pressure was already sufficient to deliver gas to all destinations, including the Rokan Block,” Laode Sulaeman, director general of oil and gas at the energy ministry, said on Wednesday.
The pipeline leak, which occurred on Jan. 2, disrupted gas supplies needed to power oil production facilities at the Rokan Block in Riau, Indonesia’s largest producing oil field. As a result, national oil output fell by about 15–17% to around 500,000 barrels per day, Laode said.

Oil production at Rokan, operated by Pertamina Hulu Rokan, is expected to return to normal within the next two days as gas supply stabilises. However, the prolonged disruption over roughly 20 days has resulted in cumulative production losses of about 2 million barrels.
“To compensate for that loss, we have homework to increase national production by around 5,000 to 6,000 barrels per day,” Laode said, adding that authorities are seeking incremental output from other oil fields to help offset the shortfall.
Gas flows had been partially restricted in recent days due to safety concerns following repeated explosions, before being gradually restored to full capacity. The energy ministry said repairs to the pipeline have now been completed.
The government is working with SKK Migas to accelerate additional production from smaller fields, particularly in South Sumatra, to support national output and safeguard the country’s 2026 oil lifting target of 610,000 barrels per day.
